Satellite simulator will be used in support of UK sovereign space capability programme. Acting on behalf of Army HQ, Defence Equipment and Support (DE&S) in the UK MoD is seeking to procure a modular, event-driven and fully data representative satellite simulator for use in design, development, integration, test and operation of space segment assets. DE&S expects to receive at least ten proposals including submissions from SMEs. It will send out invitations to tender for an £800,000 ($1.09 million) contract in mid-February 2021. The simulator, to be called ARTSIM, will be used in support of the Artemis programme to develop, test and launch a constellation of small low-Earth orbit satellites.
